3 Rolls

Hydraulic Sheet Bending Machine

The experience acquired over more than 100 years is reflected in the latest generation of 3 Roll Hydraulic Bending Machines. The 3-Roll Hydraulic Bending Machine is more economical when compared to the 4-Roll machine, but it is also capable of covering a large part of the demanding bending needs. The pre-bending operation is made with pressure between the upper and the side roll; the symmetrical arrangement of the side rolls enables pre-bending on both sides without removing the metal sheet. The bending operation is made with the correct positioning of the side rolls to create the proper radius.
